Rumor has it you can trim alum. plate with a router and a carbide bit. Are these bit just wood bits/tips????? Or are they special made for metal bits? I'm tired of filing and am lookin to clean this up a little.
I didnt use a router but thats what i did with a jig saw to cut straight lines. I trimed my motor plates to fit and they came out great. One thing i found, a continueis spray of wd40 makes the cut alot cleaner and makes the blades cut alot longer. I just bought a few cans and had a buddy sit there and spray the blade while i was cutting. i would assume it would help even if you where using a router.I think I could clamp a straight edge for the router to follow on the side that's straight
That's the beauty of the Round-Over bit. That little shiny peice is a tiny roller bearing. Set the depth so that the bearing rides about the middle of the thickness of the aluminum and have at it. The bearing rides along the edge at the depth you set and you're there. Just run that little bearing along the edge and it takes exactly what you want off and no more.Too, cool thanks Jrork. Did you do that last round cut freehand or did you make some kind of a jig??(the half round one)
Real Good info Cave!! MGo for it. Trim it up with a jigsaw. Make a jig out of plywood to the shape you want to finish off the cut. Then final cut with a 2 flute carbide plunge bit following the jig. If you try to to do this freehand you will be sorry
A 1/2" 2 flute plunge bit that's at least 2.5" long will work fine. If you want just want to clean up the edge on that circular area then use a dremel with the round mini drum attachment. A belt sander works great to clean up the flat edges.
Did you ever try to make the pump brace?
